Management & surveillance of rectal neuroendocrine tumours: a single‐centre retrospective analysis

Background Rectal neuroendocrine tumours (rNETs) are rare but are increasing in incidence. Current management and surveillance recommendations are based on low‐grade evidence. Follow‐up practices are often inconsistent and costly. This retrospective study analyses a single‐centre's experience with rNETs to assess incidence, management practices, outcomes, and guideline adherence. Methods This is a single‐centre retrospective study from Queensland Australia, spanning from 2012 to 2023. Twenty‐eight rNET cases met inclusion criteria. Examined parameters included incidence, management, outcomes and adherence to European Neuroendocrine Tumour Society (ENETS) guidelines. R1 resection rate was analysed for associations with resection technique and lesion recognition and recurrence rate was assessed in all patients. Results This study shows an increasing incidence of rNETs during the study period, reflecting a global trend. R1 resection rate at initial endoscopy was 75%. There was a general lack of advanced endoscopic techniques utilized and poor lesion recognition, however a statistically significant correlation was not established between these factors and an R1 result (P
